问题 The degree of a beach’s downward slope depends on its composition of deposits as well as on the action of waves across its surface.
选项 A、sediments
B、segments
C、substances
D、sources
答案 A
解析 本题考查形近词辨析。四个选项均为以s开头的复数名词，A选项意为“沉积物；沉淀物”，B选项意为“环节；部分；段落”，C选项意为“物质，材料；实质，内容”，D选项意为“来源，产地”，选项之间的意义无交叉。题干替换词意为“沉淀物”，语句中its指代beach，沙滩的构成应该是某种物质，因此可以排除完全无关的B、D选项，再按照沙滩、坡度、海浪冲刷等提示的语境选定答案为A。
